Technical characteristics of heat shrinkable film

With the improvement of the quality of life, the requirements for the diversification of packaging film and shrink film are also increasing. PE heat shrinkable film is used for the sales and transportation of various products, and its main function is to strengthen, cover and protect the product. The heat shrinkable film requires high puncture resistance, good shrinkage and corresponding shrinkage stress. When shrinking, the film cannot produce holes. The shrink film is often used outdoors, so UV sunscreen should be added. High flexibility, not easy to break, strong blasting force, impact resistance, tear resistance, strong traction, and can replace the packing box. The shrinkage rate is high. After heat shrinking, the items can be tightly wound together to make PE straight-through bags (openings at both ends of the bag). After heat shrinking, the two ends of the openings can be lifted to bear 15 kg weight, which is convenient for transportation and transparency Good, the product can be displayed after the light transmittance reaches 80%, and there may be no tangible promotion of the product, which reduces the distribution errors in the logistics barrel. Not only can it obtain moisture-proof, waterproof, dust-proof, and packaging effects, but also beautiful products and protective products. PE heat-shrinkable film is made by secondary expansion after mixing ethylene PVC resin with more than 10 kinds of auxiliary materials. The transparency, strength, and shrinkage rate can be adjusted freely according to user requirements, and the operability is strong.
